To all whom it may concern 7 Be it known that I ROBERT F. G'OWEN, a citizen of the United tates, residing at'New York, county and State of New York, have] permit ready plugging in or taking out of the inductance coil element.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangementof parts, all as will be more fully'hereinafter set forth, as shown by the" accompanying drawings,-and finally pointed out in the appended claims.

' inductance coils frequentlyrequired, especially in radio work, is difficult to obtain in this manner.

"It is among the several purposes of my presentinvention toovercom'e these objectlons and to provide mechanical means for adjusting a coupling between inductance coils which will permit a fine degree of adjustment and permanency of adjustment once obtained. While I have shown and will now describe inductance coil mountings especially designed for radio work, I desire it' to be understood that I do not intend to limit or restrict the invention to this specific use as the same may be applied wherever loose coupled coil can be utilized. I

In Fig. 1' of the drawings 1 show a mounting applied to a flat'base 1- adapted to rest on a fiat surface such as a disk, table orlthe like, where the balance of the appa ratus is stationed. Secured in, any suitable manner to the base '1 is a standard 2 for supporting the coil mount which consists of a bracket 3 in which is readily secured a member 4 having male and female electrical plugs 5 and 6 respectively. The stationary member' l is disposed centrally in the bracket 3 and on each side thereof extending through the arms of the bracket are shafts 7 and 8 on which are mounted to rotate therewith members 9 and 10, each provided with male .and female conducting plugs 5 and .6 respectively similar to the structure of the stationary plugl. Mounted on the shafts 6 and 7 are gear wheels 11, which gear wheels mesh with gear wheels 12 mounted on the shaft 13 which is rotatable, extending through the bracket 3 and is provided at its upper end with a knob 14. From the foregoing it will be seen that upon'rotation of either unit 14: manually or otherwise the rotatable member 9 or 10 is moved about its pivot to the desired degree. The inductance coils are illustrated at 15 and are shown as of the self-supporting type, that is, they are cylindrical and aresecu'red to the coil bracket 16 by means of a strap 17 screwed into the member 16. The member 16 is provided with the male and female plugmembers l8 and 19 respectively sothat to connect the inductance coils in their operative position it is merely necessary to plug in the inductance coil structure so that the male and female members of the respective plugsmay engage each other. I make no claim in this present application to the structure of coil or the strap support therefor as the same forms the subject matter-of separate applications for patents therefor. I11 the illustration of Fig. 1 to show the structure of the member 4: the central inductance coil has been slightly withdrawn from its-operative position. The

structure of Fig. 3 is similar tothat of Fig. 1, the only difi'erence being that the structure is set up on a vertical panel rather than on a horizontal one. It will be understood that the terminals of the respective coils are in electrical connection with the respective male and female plugs 18 and 19 in each instance and that the male and female terminals 5 and 6- of the members 4, 9 and 10 are in electrical connection with wire terminals to afford circuital connection with the balance of the circuits in the system. These terminals are illustrated in Fig. 1 at 20 and in the vertical panel arrangement of Fig.

3 theterminals are located in the rear of.

the panel 21.

Itwill be understood that, any number of coils may be used according to the use to which the system is to be put. F or examplea single radially disposed coil may be employed or one movable coil with astationary coil as illustrated in Fig. 4 or a centrally stationary coil and a manually movable coil on either side of the same as illus trated in Figs. 1 and 3.

If desiredthe gear wheel movement may be eliminated as illustrated in Fig. 4. In this arrangement the stationarymember 4: is radially secured in the bracket 3 as hereinbefore described and the movable member 30 mounted on the shaft 31 as above explained is rotated after the coil 15 is in sertedin place through its cooperating male and female plug terminals in a manner which will be clearly understood.

Many modifications and changes may be made in the structure set forth without departing from the spirit and scope of my invention as pointed out in the appended claims. Therefore, having set forth the objects and nature of my invention, and a structure embodying the princi lesthereof, what I claim as new and usefu and of my own invention and desire to secure by Letters Patent is 1.
